Graphically Based Analysis of the Alznner and "Barefoot" [Supports]

When the results from the two measurement sources (CCPM and Genovation
Corp.) are examined, several patterns emerge.
The principle improvement was in the reduction of pressure or forces to
the forefoot. All measurements taken show a significant reduction of the total
forces in this area. This appears to have been accomplished without creating
The high mid-foot topographic contours are almost certainly responsible
for this and actually seem to have the benefit of providing generalized
stability to the foot. In terms of integrated usefulness, this appears to have
been accomplished while providing unusually effective plantar support. The
static and dynamic data support this as well as the graphics exhibiting
shortening of the foot, etc. Observable in the dynamic graphics are positive
changes in the medial column, changes in the pressure patterns showing enhanced
Since the device is a "neutral" [support] without posting varus/valgus,
etc., and the remainder of the device seems well designed but possibly not
responsible for these changes, it seems that the high midfoot topographic
contours may be a functional approach in some [support] designs. Given that
most conventional designs yield a slightly plantarflexed (after posting, etc.)
foot, here we have a device apparently showing functional promise after
repositioning of the foot in a dorsiflexed position. Also noted were the
unusual changes in the center of pressure.
Sagittal plane stability has been noted throughout the study by center
mass "tracking" through the longitudinally averaged axis and with other dynamic
data and graphic result.
The Alznner® [support] appears to be an unusual design providing both
support and stability with little unwanted secondary effect.
Evaluation of the Alznner [Supports]
Biomechanics Evaluation Laboratory,
College of Engineering Michigan State University
This study was conducted in two phases. The first phase involved three
subjects who had never worn Alznner® [supports]. Kinetic (force), kinematic
(motion) and dynamic electromyography (EMG) data was collected on these subjects
during walking. Each subject was tested twice.
The second phase of the study utilized three subjects who had worn
Alznner® [supports] continuously for over one year. Kinetic data only were
collected on two of the three subjects during walking with the [supports].
Kinetic and kinematic data were collected on the third subject while walking
with and without [supports]. In addition, a balance evaluation was performed on
all three subjects during standing in various positions.
Purpose of the Study:
Biomechanical evaluations performed previously at Michigan State University have
shown that shoe [supports] can bring about a change in body movement and muscle
and joint function in only two ways:
＊ It can change the motion of the foot therefore altering ankle, knee and
hip joint motion and upper body movement and/or
＊ It can change the forces and torques placed on the body by altering
their distribution on the plantar surface of the foot resulting in a change
in the Center of Gravity (CG) of the body. This is referred to as altering
the path of the Center of Pressure (COP) on the bottom of the foot.

The present work evaluated sagittal plane standing balance and
stability in three foot conditions. The foot conditions were barefoot, Alznner®
[supports] and custom [supports]. Balance was assessed during normal standing
while a 200 Newton load was applied to the subjects, and while standing with the
load. The load was directed downward and anterior to the ankle joint. It
therefore created a《dosiflexor》torque which was resisted by the calf
muscles. Center of pressure under the right foot and EMG from the Gastrocnemius
and Anterior Tibialis muscles were evaluated.
The principle result was the improvement in balance and stability
during the dynamic load application phase with the Alznner® [supports]. The
load was applied over a period of nearly three seconds and the load caused the
subjects to lean forward and the Gastrocnemius muscle EMG increased during this
time. While using the Alznner® [supports] the forward movement of the center of
pressure and the magnitude of the EMG were less compared to the other
conditions. These results indicate the subjects were better balanced and more
stable with Alznner® [supports] during dynamic, anterior loading. These results
also suggest that the Alznner® [supports] may improve balance and stability
during other dynamic tasks.
The smaller increase in Gastocnemius EMG with the Alznner® [supports]
compared to the other conditions indicates that less muscular effort was needed
to maintain balance in this condition. The reduced muscular effort may provide
greater endurance for people while performing dynamic activities.
The EMG comparisons while the subjects were standing and holding the
load were not statistically significant. However, the peak and mean
Gastrocnemius EMG sample means for the Alznner® [support] were lower than those
for other conditions. The non-significant result may be a Type II statistical
error due to low power. These results may change when the total sample (10 or
more subjects) is analyzed.
